1 ed certain new and useful Improvements in Line and Column Gages for Adding-Machines, of which the following is a specificatron.

The object of the present invention is to provide a gage of simple and effective construction adapted to serve the purpose in adding and listing machines or machines of like-character of'locating the horizontal line along which it is desiredto print or the line along which printing has last beendone, the gage also serving to locate any particular decimal or columnar space in such line.

The gage of the present invention requires very little space to accommodate it in the organized adding andlisting machine and. requires no adjustment or manipulation by the user of the machine. when the platen on which the printing is done is thrown back out of printing position into proper position for inspection of. the work or ust'nient of the paper overlying the platen, the gage autoinatically takes up the correct position for exactly locating the printing line on the paper and for guiding the operator in laterally positioning the platen Where a laterally shiftable paper carriage is employed.

In the accompanying drawings, which form part of this specification, Figure 1 represents the gage in perspective as applied to the back panel of the casing of an adding and listing machine Fig. 2 represents vertical cross section of a portion'of an adding and listing machine having the gage applied thereto, the platen being represented in.

rinting position; .Fig. 3 is a view similar to rig. 2 but representing the platen thrown back out of printing position; and Fig. 4. is a fragmental top plan view with the parts relatively positioned as in Fig. 3.

Referring firstto Fig. 1, the gage comprises a metal plate 2 curved from front to rear and formed with a straight rear edge and graduations on its upper surface along such edge also legs 3 formed integrally with the plateand attaining, through their attenuation, sufiicient resiliency for the purposes of the automatic operation of the gage hereinafter described and already alluded to.

The above described character of the gage gives it a bifurcated form providing a wide opening between the upper portions of the legs, and through this opening the type plates of the. adding and listing machine are projected in the printing. T he back )anel of the casing of the adding machine is designated by the numeral l in Fig. 1 and it has analpper extension 5 curved in the same general direction as the gage plate. This panel extension is, as usual, formed. with a rectangular opening and the gage projects from the interior of the machine through that opening for cooperation with the platen. The gage is fastened to the machineby screws 6 and clamp plates 7 overlying the lower ends of the gage legs 3 as shown in Fig. 1, and clamping the same against the inner side of the panel 4. These screws preferably enter portions of the usual bracket 8, (Figs. 2 and 3) which is fastened against the outer side of the panel 4 and constitutes a support for (he laterally movable paper carriage.

ortion of the latter which embraces said liracket with interposed ball bearings, is designated by the numeral 0 and the roller platen. which it carries is designated by the numeral 10. This platen is, as usual, mounted. in a rocking frame 11 secured to a rock rod or shaft 12,journaled in the base 8). The two positions of the platen are determined by the abutment of shoulders 13-"of one of the side plates of the frame 1], against a lug 14 "he base When the platen is in its forward or prin.t

ing position as illustrated in Fig. 2, it bears against the upper portions of the legs 3 of the gage and presents the paper to be printed upon in the opening of the gage. The resiliency of the gage legskeepsthe same and the gage plate constantly in contact with the platen and when the latter is swung back to the position illustrated in Fig. 3, the straight cdge'of the gage plate will be prcssin against the platen or the paper overlying t e same.

The gage is so proportioned and arranged,

with relation to the platen that when the latter has assumed its rcarmost position, as illustrated in Fig. 3, the straight edge of the gage will mark or denote the horizontal line along which the printing will be done if the platen is rocked forward without being turned in its own bearings. This is illus- "l as llO.

trated in Fig. 4, where a designates a sheet of paper overlying the platen and having had rlnted upon it an amount, via, 34269.70. it will be obvious that the graduationmarks upon the gage late constitute a uide by which to proper y locate the paper aterally, either by adjustment of the paper itself or laterally shifting the platen.

The gage plate is preferably made with frame or case and the platen movable toward and from the same of a gage mounted on the frame or case and spring-pressed into engagement with the platemeaid gage GOD?" sisting of a plate and resilient legs which supply'the spring pressure.

2. The combination with the machine frame or case having an opening, and a platen movable toward and vfrom said opening; of a gage at the opening comprising a plate and resilient legs fastened to thecase, the legs being spaced apart to provide an opening on the gage to register with that on the case and the gage being spring pressed against the platen through the resiliency of. its legs. i

3. The combination with a machine case having an opening, a laterally shiftable car liege mounted on said case, a frame mounted to rock on said carriage, and a roller platen on said frame opposite the opening in the case; of a line and column gage at they said opening comprising-a, graduated plate and supporting legs attached to the machine case, said gage being sprin pressed into engagement with the platen t ough the resili ency of said legs.

4. The combination with a machine case having an opening, a laterally shiftable carriage mounted on said case, a frame mounted to rock on said carriage, and a roller platen" on said frame opposite the opening in the case; ofav line and. column gage at the said opening comprising a graduated plate and supportin le s attached to the machine case, the egs eing resilient and serving to yieldinglyengage the gage with the platen.

5.- The combination of anupright framepiece or support, a laterally sliding carriage mounted on the rear thereof, a rocking frame mounted upon said carriage with provisions for limiting its range of movement to approxi mately forty five degrees, a roller platen 1 journaled in said rocking frame and normally occupying a forward position adjacent the upright frame-piece and adapted when rockedback to have its journal brought into the vertical plane of the rocking-frame journal, and a gagemounted upon the upright frame-piece or so. port and projecting upwardly therefrom 1n front of the platen and normally beyond the same, said gagev being spring-pressed against the platen and of open-center formation normally uncovering the impression area of the platen'and having an end edge normally out of contact with the Y laten but adapted when the latter is rocked g ck to come into close contact therewith under the spring pressure,
